Visualization of the Parameters and Changes of Signals Controlling the Operation of Common Rail Injectors

Abstract

The electromagnetic injector in the Common Rail system is the actuator directly responsible for fuel injection. Its proper operation is enabled by ensuring appropriately shaped changes of the electric signal worked out by the output stage of the controller. This paper determines the repeatability of the control signal and the possibility of using this signal for the diagnostics of the electrical part of the injector.

Identification of a model of the crankshaft with a damper of torsional vibrations

“…The proposition of model identified on the basis of experiments may serve as an important tool in the design process of systems eliminating vibrations and the measurements of engine vibrations. It can also be a valuable source of diagnostic information about the technical condition of piston engines, in particular, torsional vibration dampers [20][21][22][23][24][25]. The phenomenon of vibration coupling in the crankshaft transfers oscillations between angular and transversal displacements.…”

“…Dependencies Eqs. (21) and (22) make no sense without defining the relevant metrics. It is convenient to define the distance in frequency domain in the following way:…”

Analysis of bending and angular vibration of the crankshaft with a torsional vibrations damper

“…4). The engine was measured on a test stand [14,15]. Thus, it was possible to be independent from the moment disruptions on the engine shaft.…”

Effect of the Pilot Charge Injection Advance Angle on the Operating Parameters of a Dual-Fuel Compression-Ignition Engine Fuelled With Biogas

“…It is also important to stress that the use of these fuels for energy purposes reduces the emission of methane spontaneously released from, among others, dumping sites, which is ca. 25 times more harmful to the ozone layer than carbon dioxide [7].…”
